JESSE BLINN, OF ROCKFORD, ILLINOIS.

IMPRCVEMENT IN GATES.

Specification forming part of Letters Patent No. 135,463, dated February 4, 1873.

To all whom it may concern:

Be it known that I, JESSE BLINN, of Rockford, in the county ot' Winnebago and State of Illinois, have invented a new and useful Improvement in Gates; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

Figure l is a perspective view of my improved gate and Fig. 2 is a vertical section taken transversely of the gate, and longitudinally ofthe rock-shaft which operates it.

The object of the invention is to construct a gate which can be readily opened and closed by a person who wishesto pass through without alighting from his horse or carriage, as the case maybe, a-nd which shall be cheap, durable, and easily operated. To this end the invention consists in a certain new combination and arrangement of parts which will he hereinafter fully explained. Y

In the drawing, A is a longitudinal. sill, and B a transverse sill, both of which are tirmly bedded in the ground and usually about on a level therewith. C CI G2 are vertical posts rising from sill A. a is a track of either wood or metal mounted upon that portion of sill A which lies between posts O1 C2. D is a girt or rail supported between posts C C2, and carries another track, d. E is the gate mounted upon friction-rollers, shown in dotted lines at e, the rollers traversing the tracks a d. b is another friction-wheel on a stud rising from sill A or B to properly confine the bottom of the gate to post G2. el e2 c3 are track-clearers employed to remove obstructions from the path of the carrying-wheels. e4 is a tonguepiece projecting from the front post of the gate and made to engage with a spring-clasp, c, when the gate is closed, to secure it against accidental opening. c5 is a spur or clamp attached to post G2 in such position as to enter a groove out in the under side of the top rail ofthe gate, and thus maintain the upper side of the gate in a vertical position when itl is Ythem up.

opened. The construction and relative ar ran gement of these parts are clearly shown in Fig. 2. F is a rock-shaft supported .in posts B1 B102. A roc-king motion is .imparted to this shaft bymeans of crank-arms or levers G and pulls g. As the pulls are stift' they serve not only to pull these arms down but to thrust The rocking motion of shaft F is transferred to arm F', which is connected with opposite ends of the gate by chains f.

rEhe operation of these devices will be readily understood without further explanation,

- In Fig. 1, g1 is a cord or chain attached to the outer or free end of levers G and passing over' a brace or post, g2, at the heel end of the lever, thence to the lower end of pull g, within convenient reach ofthe operator, who can by pulling upon said rope close the gate in the same manner as he would by pushing up the pull.

I do not wish to be understood as claiming broadly a device for maintaining the gate in a vertical position, but my curved guard or clamp e5 is found to be very convenient when used in combina-tion with the arm F and chains f, because it is desirable to arrange said arm in close proximity to the gate in order that the chains may draw nearly ina lille with the track upon which the gate moves, for which reason it is not convenient to sup- `port the gate hy a post upon that side.

Having now described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. The combination, with the gate, of the rock-shaft F, vibrating arm F', chains f, friction-roller b, and clamp e5 engaging with a groove in the rail of the gate, substantially as and for the purpose set forth. I

2. The combination ot' the track-clearers el e263 with the gate E, substantially as described.

This specification signed and witnessed this 2d day of September, 1872.

JESSE BLINJ.
